Westland Wapiti biplanes and five Indian pilots. The Indian pilots were led by RAF Commanding officer Flight Lieutenant (later Air Vice Marshal) Cecil Bouchier. The first five pilots commissioned into the IAF were Harish Chandra Sircar, Subroto Mukerjee, Bhupendra Singh, Aizad Baksh Awan and Amarjeet Singh. A sixth officer, J N Tandon had to revert to logistics duties as he was too short. All of them were commissioned as Pilot Officers in 1932 from RAF Cranwell. Subroto Mukerjee later went on to become the IAF's first Chief of the Air Staff. Subsequent batches inducted before World War II included Aspy Engineer, K K Majumdar, Narendra, Daljit Singh, Henry Runganadhan, R H D Singh, Baba Mehar Singh, S N Goyal, Prithpal Singh and Arjan Singh. World War II (1939–1945) During World War II, the IAF played an instrumental role in halting the advance of the Japanese army in Burma, where the first IAF air strike was executed. The target for this first mission was the Japanese military base in Arakan, after which IAF strike missions continued against the Japanese airbases at Mae Hong Son, Chiang Mai and Chiang Rai in northern Thailand. The IAF was mainly involved in strike, close air support, aerial reconnaissance, bomber escort and pathfinding missions for RAF and USAAF heavy bombers. RAF and IAF pilots would train by flying with their non-native air wings to gain combat experience and communication proficiency. Besides operations in the Burma Theatre IAF pilots participated in air operations in North Africa and Europe. In addition to the IAF, many native Indians and some 200 Indians resident in Britain volunteered to join the RAF and Women's Auxiliary Air Force. One such volunteer was Sergeant Shailendra Eknath Sukthankar, who served as a navigator with No. 83 Squadron. Sukthankar was commissioned as an officer, and on 14 September 1943, received the DFC. Squadron Leader Sukthankar eventually completed 45 operations, 14 of them on board the RAF Museum’s Avro Lancaster R5868. Another volunteer was Assistant Section Officer Noor Inayat Khan a Muslim pacifist and Indian nationalist who joined the WAAF, in November 1940, to fight against Nazism. Noor Khan served bravely as a secret agent with the Special Operations Executive (SOE) in France, but was eventually betrayed and captured. Many of these Indian airmen were seconded or transferred to the expanding IAF such as Squadron Leader Mohinder Singh Pujji DFC who led No. 4 Squadron IAF
